Apr 16, 2024 · The adhesives in tape, known as pressure-sensitive adhesives (PSA), rely on physical reactions, utilizing materials like silicones, acrylics and rubbers enhanced with tacky resin for increased stickiness. PSAs form bonds through two main processes: wetting and van der Waals forces.

Photo: PVA (polyvinyl acetate) is a typical household adhesive, commonly used for sticking wood together. Here's a small sample that I squirted out, next to its container. According to historians and archeologists, adhesives have been usedfor thousands of years—probably since Stone Age cave dwellers first applied bitumen (atarry substance used to s...
Knowing what something is called is a far cry from knowing how itworks. That was a lesson the Nobel-Prize-winning American physicist RichardFeynman(1918–1988) often used to teach. So let's forget all aboutadhesives, acetates, and acrylates and try to figure out why one thingwill stick to another. If you want a short answer, the word is "forces." Pe...
Artwork: Adhesive and cohesive forces both play a part in sticking things together. What does all this have to do with adhesives? Adhesive and cohesiveforces are also at work in glues. Let's say you want to stick togethertwo bits of wood, A and B, with an adhesive called C. You need threedifferent forces here: adhesive forces to hold A to C,adhesiv...
Now we know that adhesives work through adhesive and cohesiveforces, we need to understand a bit more about how those forcesthemselves work. Let's start with cohesive forces.As you can discover in our main article about the magic of water, water molecules jointogether with one another because they're not symmetrical. One end has aslight positive ch...
Now for the real question: what makes a gluey substance stick tosomething else? You may be surprised to hear that there's no single,simple answer—but that's not so surprising if you consider how manydifferent types of glue there are and how many different ways in whichwe can use them. For each different glue, and each different surface weuse it on,...
So what about that little Post-it® note stuck to your wall? How does that work? Look at the back of a sticky note using an electron microscopeand you'll see not a continuous film of adhesive but lots of microscopic glue bubbles,known as microcapsules, which are about 10–100 times bigger and much weaker than the glueparticles you'd find lazing aroun...
Photo: Epoxy glues are made of two substances that become sticky only when you mix them.Often they're packaged in a pair of syringes joined together, like this. Adhesives are designed to work when they leave the tube—and notbefore. Different adhesives achieve this in different ways. Some aredissolved in chemicals called solventsthat keep them stabl...
Dec 14, 2022 · How does self adhesive work? When the tape is applied to a surface, the adhesive is activated, allowing it to stick firmly. The adhesive on the glue tape works because it is pressure sensitive.

Jul 14, 1997 · When the molecules are dissimilar, as in the case of a glue molecule and a molecule of the substrate (the surface the glue is sticking to), the adhesive force holds the glue to the substrate.
